Xmodem Timing Commands

The following table lists the AXC-232++ Xmodem timing commands. Xmodem timeouts exist to accommodate potential Ethernet delays and for consistency among and within products. Any Xmodem timing command will change timing and retries for Axcess code download as well as SOFTROM transfer.

Xmodem Timing Commands

Command	Description
'TIMEOUT XX'	Xmodem timeouts via the Program Port. (Default is 10 sec.)
SEND_COMMAND	Over AXlink, where XX is from one to 50 seconds in 1-second increments.
SERIAL, 'XMTO XX'
'RETRY XX'	Xmodem retries via the Program Port. (Default is 5.)
SEND_COMMAND	Over AXlink where XX is from one to 10 in increments of one.
SERIAL, 'XMRT XX'

AXlink Master Statements

The following table lists the AXlink Master statements for the AXC-232++.

AXlink Master Statements

Statement	Function
MIN_TO	Activates a channel or variable for a minimum amount of time-even if the corre-
	sponding device-channel is released. The time duration is determined by
	SET_PULSE_TIME.
ON[AXC_232,	Executes PUSH[0,channel] within AXC-232++.
channel]
OFF[AXC_232,	Executes RELEASE[0,channel] within AXC-232++.
channel]
PULSE	Turns on a channel or variable for a certain amount of time. Once the time
	elapses, the channel or variable is turned off. The Pulse time remains the same
	value until it is changed within the program.
	Example:
	SET_PULSE_TIME(12)
	Sets the current duration of future Pulses to 1.2 seconds.
SEND_COMMAND	AXC-232++ interprets command.
AXC_232,command
SEND_LEVEL	Places the variable into the CREATE_LEVEL variable, if it were defined in the
AXC_232,level,	AXC-232++ DEFINE_START section.
variable
SEND_STRING	Places the string into the CREATE_BUFFER buffer, if you defined the buffer in
AXC_232,string	the AXC-232++ DEFINE_START section. If it were not, this command trans-
	mits the string out the RS-232 port.
TO	Activates a channel or variable for as long as the corresponding
	device-channel of its Push statement is activated. When the device-channel
	referenced by the Push statement changes from off to on, the TO starts activat-
	ing the device-channel or variable in the brackets following it. When the
	device-channel of its Push is released, the TO statement stops activating its
	device-channel or variable. For this reason, TO must be found only underneath
	a Push statement.
